Early in August, I found near the edge of Mount Edgecumbe pond a nest of this Grebe—a round heap of pond-weed and rotten leaves, flattened at the top, and slightly hollowed; it was about fifteen inches wide, and six or eight thick. The top was damp, but not wet, and very warm from exposure to the sun’s rays. We drew it on shore, for it was entangled among the branches of a fallen tree, but _not attached_ to them, and presently found on the matted weed, just below the surface in the place where we had dragged it, a large white egg, excessively begrimed with dirt, doubtless from lying on the decaying leaves. On being cleansed, I found it covered with a chalky coat, easily scratched off. A few weeks after, I again visited this pond. On approaching before sun-rise, (for I had travelled by the brilliant starlight of the tropical heavens,) I saw a Grebe sitting on a new nest, in the same spot as I had found the former one: this nest was composed of similar materials, and contained four eggs. Early in December we found another nest, with the young just peeping from the egg. It is probable, therefore, that several broods are reared in a season. One of my lads, who has lived close by this pond, affirms that the birds move the nest about to different parts of the pond; and that they use the same till it will no longer hold together, and then construct a new one. He also states that they often fight during the night; and that the conquered ones resort to a smaller pond, where they may be easily captured by hand: for, by chasing them to and fro, the small pond being shallow, they at length become wearied, and will dive no more, but make for the shore, and are caught before they can fly. The flesh is dark and oily. The gizzards of all that I obtained were filled with a finely comminuted substance, rather dry, of an unctuous appearance, and mingled with short silky filaments. A close examination with a lens failed to determine its nature; but I believe it to have been principally vegetable. * * * * * * * * * *
